2 Claims. 1

This invention is a spraying device particularly of the bath shower head type.

The instant invention has to do with the construction of shower head spray nozzles and an object of the invention is to provide a simple and practical form of means for readily varying the form of the discharged spray from the head.

Another object of the invention is to provide a shower head incorporating a diffusing discharge tip having perimetral,- longitudinally directed channels and having means for regulating the nozzle discharge by relative adjustment over or as to the said tip.

Also, an object of the invention is to provide a shower head involving a fixed tip assembly and a relatively movable, spray-control sleeve which is exterior to and rear of the tip and to which access may be had without need of reaching into the range of the issuing spray when the volume of discharge is to be varied and, as to this feature, an object is to provide an adjuster for the spray which includes an axially shiftable choke sleeve fitting the tip slidably and nonrotatively and a manually rotative, non-shiftable sleeve adjusting shell.

The invention resides in certain advancements in this art as set forth in the ensuing disclosure and having, with the above, additional objects and advantages as hereinafter developed and whose constructions, combinations and sub-combinations and details of means will be made manifest in the following description of the herewith embodiment and its manner of operation and functions; it being understood that modifications, variations and adaptations may be made within the scope, spirit and principles of the invention as it is more directly claimed in conclusion hereof.

Figure 1 is a side elevation, partly in axial section, of the shower head; all parts in axial alinement.

Figure 2 is a front end elevationof the detached nozzle tip; Figure 3 is a side elevation thereof, and Figure 4 is a rear (inner) end elevation of the nozzle tip; Figure 5 being an axial section of the nozzle tip to show, diffusing channels of the nozzle tip.

Figure 6 is a side elevation of the detached. central body of the head to show its sleeve splineway and its shell retaining, annular shoulder.

The disclosed form of the head incorporates a pipe receiving joint 2 having a ball end 3 on which the head assembly is universally rotative for change of direction of the axis of the water spray.

Suitably fitted and packed on the ball 3 is an interior, hollow body 5, for flow of water from the joint 2, the body 5 having a threaded rear end 6 to receive a fastening, ball fitting nut 1 which is xed by a setscrew 1s. The outer or forward end of the body has a reduced, conical nose 8 onto which is snugly, concentrically fitted a cylindrical, discal nozzle tip 9 fastened by an axial screw l0 onto the said nose. Port holes II in the body discharge water radially to the space X back of the rear end of the tip 9.

Referring now more especially to the tip 9, the annular periphery of this is provided with longitudinal channels I3 and I4 of different depth.

For the purpose of changing the volume and spray from the head there is operatively slidable on the tip 9 a non-rotative jacket or sleeve I 5 whose front end edge overlies the channels l3-I4. The rear or inner end of the sleeve slidably fits the body 5 and has a spline key I5a shiftable along a splineway I6 therefor in the contiguous body face. An annular, non-shifting, packing ring Il in the body seals on the bore face of the sleeve.

For the purpose of reciprocating the splined sleeve I5 along the tip channels lil-I4 as desired there is rotatively mounted on the body 5 an external, enclosing shell I8 retained against end shift on the body by a stop shoulder 2l thereof in cooperation with the coupling nut 1. Therefore, the shell can rotate on the body and, by means of internal threads |8a engaging complementary threads on the regulating sleeve I5, the latter will be readily shifted axially on the rim of the channeled tip 9 to reduce or increase the water flow.

It is understood there may be as many channels as desired in the rim of the tip. These channels are shown as ending in the rear end face of the tip in inlet mouths which have an approximately U-shape in the end View. It found in actual practice that this novel diffusion nozzle causes small but substantial streams of water to issue without a noticeable fine fogging of the spray.

What is claimed is:

1. A liquid spray nozzle including a central, cylindrical, hollow body having a reduced outer nose end which has radial ports to the space thereabout for liquid fiow from the hollow body, a sleeve surrounding and sliding on a portion of the body and having an inwardly projecting key, said body having an external splineway in which the key slides, a cylindrical tip xed on 2. The nozzle of claim 1; said body having, 10

near the nose end, a peripherally extending groove, and a packing ring partly sunk in said groove and on which the bore face of the said sleeve operatively seals.
